COLORADO POTATO BEETLE 
The first Colorado potato beetle (j^;£^nioJjjn-sa decemlineata 
Say) recorded from the field, ^ a s observed on March 25 in Mississippi. 
About the middle of April this insect became decidedly troublesome in 
the Norfolk section through its feeding on eggplant in cold frames. 
An adult was first seen in this Section on April 4. By the middle of 
April eggs were hatching in the Carolinas. In Florida and the Gulf 
section during late March and early April this' insect was 'quite trouble- 
some in tomato plant beds. Late in May adults were unusually prevalent 
on Long Island, N, Y. , and by this time were doing some damage in the 
big potato-growing district about Hastings, Ela. A rather unusual- 
occurrence was reported from Michigan where the overwintering adults 
were said to have been attacking the young shoots of asparagus. As the 
season advanced, this insect became so prevalent in Suffolk County, 
N. Y. , that the usual sprayings were not sufficient to control the out- 
break. This unusual abundance extended into Pennsylvania and parts of 
Ohio, Minnesota, and Wisconsin. Owing to the very effective control of 
the beetle by insecticides it is very difficult to ascertain its status 
over any considerable territory. 
HARLEQUIN BUG 
During the late winter months the Harlequin bug ( Murgantia 
histrionica Hahn) did considerable damage in the Gulf Coast trucking 
districts to a wide variety of cruciferous plants. Late in March this 
insect was reported as seriously damaging cabbage, peas, and beans in 
Delaware; early in April it was reported from Eastern Maryland, and by 
the middle of April was seriously abundant in certain coasta? plains, 
sections of Virginia, North Carolina, and South Carolina. Towards the 
end of April reports of severe damage were received from all parts of 
Mississippi, Louisiana, Alabama, and northeastern Texas. 
MEXICAN BEAN BEETLE 
The winter survival of the Mexican bean beetle ( Epilachna corrupta 
Muls.) in the Southern States was the highest in 1929 of any year on 
record. At the Arlington, Va. F Farm 62.4 p.r cent of 1,800' beetles 
placed in the hibernation cage emerged in the Spring. This is more 
than twice as high as the record for any of the last eight years in 
Alabama. Reports from the Southern States indicate that the beetle 
was generally very numerous, especially in Alabama, Kentucky, \,ho 
Carolinas, Virginia, .and Maryland, and that much damage was done to 
the bean crop. In Ohio the percentage of survival was 2.88 per cent 
at Athens and 1.76 per cent at Columbus, both figures being higher 
than in 1928, the highest for the last five years for Columbus, and 
higher than any year for the last four years at Athens, with the 
exception of 1927, when 4 per cent survived the winter. On the 
Eastern Shore of Maryland the spring infestation was heavy, but 
droughts during the summer prevented a great increase in population. 
In some localities, however, control practices were necessary throughout
